Description

Technical Field

[0001] The utility model relates to the technical field of cotton spinning processing, in particular to a single yarn strength tester facilitating automatic feeding. Background Art

[0002] A single yarn strength tester is an experimental device dedicated to measuring the physical properties of textile yarns. Its main purpose is to test the tensile strength and elongation rate of yarns. By applying force to stretch the yarn until it breaks, the maximum bearing capacity (breaking strength) of the yarn and the elongation ratio before breaking can be measured. These parameters of the yarn have a direct impact on formulating processing techniques, improving the quality and service performance of textiles. Therefore, the single yarn strength tester is indispensable for the R & D, quality control and quality assurance links in the textile industry.

[0003] The existing patent (application number: 202221140832.X) discloses an electronic single yarn strength tester for textile product production, including a base; a display is installed on one side of the upper end of the base, a detection box is installed on the other side of the upper end of the base, a lead screw is rotatably installed in the middle of the detection box, a lead screw nut is sleeved on the upper end of the lead screw, a moving block is installed on the upper side of the lead screw nut, second fixing members are installed on both sides and the middle of the front end of the moving block, an electronic vernier caliper is installed on one side of the second fixing member, a tensile force sensor is installed on the detection box corresponding to the position of the second fixing member, and a first fixing member is installed at the bottom end of the tensile force sensor. During the rotation, the lead screw nut drives the moving block, that is, the second fixing member, to move, and at the same time, multiple groups of single yarns are stretched simultaneously, and multiple groups of single yarns are uniformly detected. The tensile force sensor detects the anti-tensile performance of the single yarn, and the electronic vernier caliper measures the length of the single yarn stretch.

[0004] The inventor found that the following problems in the prior art were not well solved during the implementation of this solution: After each test is completed, if the yarn breaks, the operator needs to manually pull the new yarn end to the measurement position and manually clamp it on the test device, and automatic feeding cannot be achieved, which is not only time-consuming but also increases the operation complexity.

[0005] In view of the above situation, technical innovation is carried out on the basis of the existing single yarn strength tester. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a single yarn strength tester facilitating automatic feeding to solve the problems of inability to achieve automatic feeding, being time-consuming and increasing the operation complexity as mentioned in the above background art.

[0007] To achieve the above object, the present utility model provides the following technical solutions: a single yarn strength tester facilitating automatic feeding, comprising a machine body and a control console. The control console is installed on the left side of the machine body. At the top of the front end of the machine body, a feeding guide plate is fixed. On one side of the feeding guide plate, two groups of guide wheels are provided. On the left side below the feeding guide plate, a lifting motor is installed. The output shaft of the lifting motor is fixedly connected with a propulsion gear. The propulsion gear is meshed and connected with a tooth rail on the right side. The tooth rail moves up and down at the machine body. On the right side of the tooth rail, a lifting block is fixedly connected. At the lifting block, a mounting seat is fixedly connected. At the top end of the mounting seat, a steering motor is fixedly connected. The output shaft of the steering motor is fixedly connected with a rotating shaft. An adjusting rod is fixedly sleeved outside the rotating shaft. On the right side of the adjusting rod, a clamping cylinder is fixedly connected. On the right side of the clamping cylinder, a clamping block is fixedly connected. The piston rod of the clamping cylinder is movably connected with the clamping block.

[0008] Preferably, on the left side below the guide wheel, an upper pressure cylinder is fixedly connected. On the right side of the upper pressure cylinder, a fixed pressing block is provided. The fixed pressing block is welded on the outer wall of the machine body.

[0009] Preferably, an inner groove is formed inside the machine body. A linear screw rod is movably assembled in the inner groove. A threaded seat is sleeved outside the linear screw rod. At the front end of the threaded seat, a lower pressure cylinder is fixedly connected. On the right side of the lower pressure cylinder, a wire-pulling pressing block is fixedly connected. The piston rod of the lower pressure cylinder is movably connected with the wire-pulling pressing block.

[0010] Preferably, a guide rail is provided on the right side of the linear screw rod. The threaded seat is sleeved outside the guide rail to form a movable sleeve connection.

[0011] Preferably, the turning angle of the rotating shaft is 0-90° in the horizontal direction.

[0012] Preferably, a driven gear is fixedly sleeved at the bottom end of the linear screw rod. A servo motor is provided on the left side of the linear screw rod. The output shaft of the servo motor is fixedly sleeved with a driving gear. The driving gear and the driven gear are meshed and connected.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: the single yarn strength tester facilitating automatic feeding not only realizes automatic feeding, completes multiple continuous tests of yarns to obtain more accurate test results, reduces the time consumed by manual feeding, realizes precise grasping-clamping and pulling-down, has high test stability and strong repeatability, but also realizes that one person can complete the test and recording, and is suitable for batch testing of yarns;

[0014] (1) After the lower pressure cylinder presses the wire pressing block to tighten the yarn until it breaks, the lifting motor starts, driving the propulsion gear to rotate. The toothed rail meshes and moves upward accordingly. The mounting seat is lifted to the yarn break position through the lifting block. At this time, the steering motor drives the rotating shaft to rotate horizontally, and the connecting rod opens. Then the clamping cylinder drives the piston rod to press towards the clamping block. After the yarn is tightened, the propulsion gear rotates in reverse, and the toothed rail descends until the clamping cylinder pulls the yarn to a certain distance below the upper pressure cylinder. Then the connecting rod horizontally flips towards the machine body again until the clamping cylinder fits onto the machine body. The clamping cylinder retracts the piston rod. After the clamping cylinder moves downward a certain distance again, it can disengage from the yarn and reset. At this time, the lower pressure cylinder pushes out the piston rod to press the yarn tightly at the wire pressing block, and then slowly pulls the yarn downward for testing. By automatically pulling in the broken yarn, manual re-aligning of the yarn is not required, and automatic feeding can be achieved, completing multiple consecutive tests of the yarn to obtain more accurate test results and reducing the time consumed by manual feeding.

[0015] (2) By setting the lower pressure cylinder, upper and lower pressure cylinders, servo motor, driving gear, driven gear, and linear screw, the lower pressure cylinder pulls the yarn downward to test various data during yarn stretching. When the lower pressure cylinder moves upward, it can reset and clamp the yarn. Driven by the servo motor, the driving gear rotates, driving the meshing driven gear to rotate, thereby controlling the number of rotations of the linear screw to drive the threaded seat to move up and down, achieving precise grasping - clamping and pulling down, with high test stability and strong repeatability.

[0016] (3) By setting the propulsion gear, toothed rail, clamping cylinder, and steering motor, the instrument drives the clamping cylinder to move up and down through the meshing of the propulsion gear and the toothed rail. The steering motor drives the rotating shaft to drive the clamping cylinder to swing outward or fit onto the machine body, facilitating its up and down movement and clamping of the yarn, and its movement and reset will not be affected by the position of the lower pressure cylinder. The console controls various parameters of the yarn test, and one person can complete the test and recording, which is suitable for batch testing of yarn. Description of the Drawings

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-3 , a single yarn strength tester facilitating automatic feeding, comprising a body 1 and a console 17. The console 17 is installed on the left side of the body 1. The feeding guide plate 2 is fixed at the top of the front end of the body 1. Two groups of guide wheels 3 are arranged on one side of the feeding guide plate 2. The lifting motor 19 is installed below the left side of the feeding guide plate 2. The output shaft of the lifting motor 19 is fixedly connected with the propulsion gear 18. The propulsion gear 18 is meshed and connected with the tooth rail 16 on the right side. The tooth rail 16 moves up and down at the body 1. The right side of the tooth rail 16 is fixedly connected with the lifting block 20. The mounting seat 21 is fixedly connected to the lifting block 20. The steering motor 22 is fixedly connected to the top of the mounting seat 21. The output shaft of the steering motor 22 is fixedly connected with the rotating shaft 23. The connecting rod 24 is fixedly sleeved outside the rotating shaft 23. The right side of the connecting rod 24 is fixedly connected with the clamping cylinder 25. The right side of the clamping cylinder 25 is fixedly connected with the clamping block 6. The piston rod of the clamping cylinder 25 is movably connected with the clamping block 6;

[0024] Specifically, as Figure 1 , Figure 2 and Figure 4As shown, after the lower pressure cylinder 8 presses down the wire-pulling block 7 to pull the yarn until it breaks, the lifting motor 19 starts, driving the propulsion gear 18 to rotate. The toothed rail 16 meshes and moves upward accordingly. The mounting seat 21 is driven by the lifting block 20 to rise to the yarn break position. At this time, the steering motor 22 drives the rotating shaft 23 to rotate horizontally, and the connecting rod 24 opens. At this time, the clamping cylinder 25 drives the piston rod to press towards the clamping block 6. After the yarn is tightened, the propulsion gear 18 rotates in reverse, and the toothed rail 16 descends until the clamping cylinder 25 pulls the yarn to a certain distance below the upper pressure cylinder 5. Then the connecting rod 24 horizontally flips again towards the body 1 until the clamping cylinder 25 fits against the body 1. The clamping cylinder 25 retracts the piston rod. After the clamping cylinder 25 moves downward a certain distance again, it can disengage from the yarn and reset. At this time, the lower pressure cylinder 8 pushes out the piston rod to press the yarn tightly at the wire-pulling block 7, and pulls the yarn downward slowly again for testing. By automatically pulling in the broken yarn, there is no need to manually re-arrange the yarn, and automatic feeding can be achieved.

[0025] Embodiment 2: A driven gear 13 is fixedly sleeved at the bottom end of the linear screw 12. A servo motor 15 is arranged on the left side of the linear screw 12. The output shaft of the servo motor 15 is fixedly sleeved with a driving gear 14. The driving gear 14 and the driven gear 13 are meshed and connected. A upper pressure cylinder 5 is fixedly connected to the left side below the guide wheel 3. A fixed block 4 is arranged on the right side of the upper pressure cylinder 5. The fixed block 4 is welded to the outer wall of the body 1. An inner groove 10 is opened inside the body 1. The linear screw 12 is movably assembled in the inner groove 10. A threaded seat 9 is sleeved outside the linear screw 12. The front end of the threaded seat 9 is fixedly connected with a lower pressure cylinder 8. The right side of the lower pressure cylinder 8 is fixedly connected with a wire-pulling block 7. The piston rod of the lower pressure cylinder 8 is movably connected with the wire-pulling block 7. A guide rail 11 is arranged on the right side of the linear screw 12. The threaded seat 9 is sleeved outside the guide rail 11 to form a movable sleeve.

[0026] Specifically, as Figure 1 and Figure 3 shown, the lower pressure cylinder 8 pulls the yarn downward to test various data during yarn stretching. When the lower pressure cylinder 8 moves upward, it can reset and clamp the yarn. Driven by the servo motor 15, the driving gear 14 rotates to drive the meshed driven gear 13 to rotate, thereby controlling the number of turns of the linear screw 12, so as to drive the threaded seat 9 to move up and down, realizing precise grasping-clamping and pulling down.

[0027] Embodiment 3: The flipping angle of the rotating shaft 23 is 0 - 90° in the horizontal direction;

[0028] Specifically, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the instrument drives the clamping cylinder 25 to move up and down through the engagement of the propulsion gear 18 and the toothed rail 16, and drives the clamping cylinder 25 to swing outwards or fit to the machine body 1 by driving the rotating shaft 23 through the steering motor 22, so as to facilitate its up and down movement and clamping of the yarn, and it will not be affected by the position of the lower pressure cylinder 8 during its movement and reset. The console 17 controls various parameters of the yarn test.

[0029] Working principle: When the present utility model is in use, after the yarn is put down, a part of the top end of the yarn is clamped by the upper pressure cylinder 5, and then a part of the bottom end of the yarn is clamped by the lower pressure cylinder 8. Driven by the servo motor 15, the driving gear 14 rotates to drive the driven gear 13 engaged therewith to rotate, thereby controlling the number of turns of the linear screw 12, so as to drive the threaded seat 9 to move downwards, and slowly move for testing. When the yarn breaks at the limit, various data of the yarn test can be obtained. After the lower pressure cylinder 8 presses the wire pulling block 7 to break the yarn, the lifting motor 19 is started to drive the propulsion gear 18 to rotate, and the toothed rail 16 meshes and moves upwards accordingly. The mounting seat 21 is driven by the lifting block 20 to rise to the yarn break position. At this time, the steering motor 22 drives the rotating shaft 23 to rotate horizontally, and the connecting rod 24 opens. At this time, the clamping cylinder 25 drives the piston rod to press towards the clamping block 6. After the yarn is pressed tightly, the propulsion gear 18 rotates in reverse, and the toothed rail 16 descends until the clamping cylinder 25 pulls the yarn to a certain distance below the upper pressure cylinder 5. Then the connecting rod 24 horizontally flips towards the machine body 1 again until the clamping cylinder 25 fits to the machine body 1. After that, the clamping cylinder 25 retracts the piston rod. After the clamping cylinder 25 moves downwards for a certain distance again, it can disengage from the yarn and reset. Then the lower pressure cylinder 8 pushes out the piston rod at this time to press the yarn tightly at the wire pulling block 7, and pulls the yarn downwards slowly again for testing. By automatically pulling in the broken yarn, there is no need to manually re-arrange the yarn, so that automatic feeding can be achieved and multiple continuous tests of the yarn can be completed.
